EUGENE BAIHA WILLIAH .ionn miinnrrr; AND HENRY JOSEPH LIPP or nEw Yomz, JY. anvnn'risme-cnocx.

To all whom it concern citizen of the United States, and resident of the borough of Manhattan, city, county,

and State of New York, and WILLIAM J MERRITT and HENRY J. LngPE,"Jr., citizens of the United States, and residents of the borough of Bronx, county of Bronx, city and State of New York, haveinvented certain new and useful Improvements in Advertising-Clocks, of which the following is a specification.

The device, the subject of this invention is intended an electric clock of 'the self winding type and one that is provided with a marine or hair spring escapement. V

In. constructingliour devioe we have intended that-it sha be simple and complete mits operation and although provided with a springv we arrange that the spring shall be of small capacity and thatit shall be rewound each hour to an extent equal to the amount freed or unwound during the hour.

Our clock is provided with the smallest numberof movable parts that appears possible, that is we have omitted many of the gear and pinions usually found in clocks driving directly from the spring to a time 7 which maybe sheet tin of suitable,

element and controlling the drive so that the proper spacing or proper speed of the time recording elements may be obtained.

The mechanical construction and details of op'erationwill appear in full as the specification progresses.

The following is what we consider the best means of carrying out this invention.

The accompanyingdrawings form a part of this specificatiom'in which Figure 1 shows in elevation our completed device. Fig. 2' is a side elevation of certain parts of,- the gear mechanism and is-on a larger scale. Fig. 3 is a sideelevation.

Similar reference numerals indicate-like parts in all the figures where they' appear.

In developing this invention we have constructd it to be used with an ordinary car card, such cards .as. are placed between guides arranged adjacent to. the inside of the roof of an ordinary streetcar. The card portion as indicated at l, is formed of metal thickness, the metal has its edg fdlced P ward and flanged as shown at 2, to produce a Y surface which may be engaged in the p j guides secured ;within the car. By forcing Be it known that'we, EUGENE BANTA', a

the metal upward we produce a sufiicient depth for theaccommodation and reception of the parts now to be described.

" Patented Nov. 14, 1916;

Projecting from the face of the card or metal sheet and formedintegral therewith are aplurality of-ways'as indicated at 3, 4, 5, 6, 7, 8, 9, and 10. Arranged together in pairs and adapted to. receive-between ,them sultable strips of card board uponfwhich advertising matter may be printed or produced. These ways utilize about one half of'the surface of a card, and upon the other half of the surface of the-card we produce a clock dial asindicalted at 11. In our drawings we have shown a glass'dial secured-in a bezel 12 which may beformed integral with .the plate, or metal sheet but we desire it. understood that we may print-or produce the dial upon the metal leaving the hands which operate upon the' dial exposed or 'coveredby anadditional glass disk.

The clock proper is constructed with a center arbor 13, to which a minute hand 14 is secured. Upon this wearrange a-gear 19 and parallel to this arbor we arrange an arbor 15 which supports a spring 16 and spring-casing therefor. A ratchet wheel 17.

is also secured upon the shaft 15 and loosely operating upon this shaft is a. gear 18' in mesh with the gear 19 which is secured upon the center arbor. A. gear 20 is secured to,

and is rotated with the gear 18, through the spring shall through the train of gears described impart to the minute hand a proper and well understood speed of rotation. The

e'scapement which is of an ordinary charac ter provided with a ratchet 24; and balance wheel 25 has a pinion directly in mesh with the gear 18.

Within "the clock and adjacent to the works thereof we have arranged an electromagnet 26 provided with an armature 27 a spring contact 34. From the spring pivoted to a suitable support as shown at 28, to the free end of the armature 27 we secure a ratchet lever 29 which engages the spring ratchet 17. The lever 29 is held between suitable guides 30 and isretrieved by means of a spring 31.

The contact making device consists of a wheel 32 provided with a pin 33, this wheel is rotated directly from the. minute wheel as shown and in contact with one face of the wheel we arrange a spring contact member 34, and a second spring contact member 35 ii adapted to be engaged by the pin 33 as s own.

The source of electrical suppl consists of a battery having a plurality 0 cells as indicated at 36, 37 and 38. This battery may be supported upon a cleat 39 formed integral with the metal plate or card and between guides 40 and 41 also formed integral with the plate or card 1. A lead wire from the battery is connected to the electromagnet 26 and a second lead .wire engages the contact 35 we extend a wire to the opposite end of the electromagnet. We may arrangeso that the electromagnet will receive one impulse each hour, the impulse will draw the armature toward the magnet and partially rotate the ratchet 17 although the spring may operate the clock for three or four hours oreven more, foraccuracyand convenience we prefer that the spring shall be rewound at least once every hour.

One of the most important features of our constructionrests in the fact that this clock will operate even though arranged upon an angle or out of the perpendicular, this is extremely important in the use of this clock in connection with car cards or similar advertising devices.

Having carefullyand fully described our cure by Letters Patent is:

1. A clock having a spring arbor, a spring thereon acasing surrounding saidspring and a gear upon said casing, a second arbor having a thimble" rotatable thereon and supporting aclockhand and a plurality of gears one of which is in mesh with said first mentioned gear, a second thimble upon said, spring arbor aplurality of gears secured thereto and rotatable therewith, one

of which is in mesh with one of the gears on the first mentioned thimble, and a sixth gear secured to the second said arbor and in mesh with a gear upon the second said thimoble and another clock hand upon the arbor of, and adapted to; be operated by the said sixth gear. 7 v

2. A clock having a spring arbor, a spring invention what we claim and desire to se- I thereon a casing surrounding said spring and a gear upon said casing a second arbor having a thimble rotatable thereon and supporting a plurality of gears one of which is in mesh with said first mentioned gear, a

second thimble upon said spring arbor, a
